Introduction to the kiln, what the kiln does

kiln (kiln; furnace;oven is a refractory material used to fire products, and it is an essential facility in pottery molding. It has developed from the open-air piling and digging pit building in the primitive society to the steamed bun-shaped flame kiln, the semi-inverted flame horseshoe-shaped kiln, the Banpo dragon kiln, and the duck egg-shaped kiln, and has developed to the current indoor gas kiln and electric kiln.

Kiln or stove is a refractory material made of equipment used to fire products, and it is an essential facility in pottery molding. Generally, it is made of bricks and stones, and can be made into various specifications according to needs, and can be operated by combustible gas, oil or electricity. Human beings have a history of tens of thousands of years of ceramic firing, and have accumulated rich kiln styles and experience.

Classification of kilns: firewood kiln: firewood as fuel, is the inheritance of the ancient kiln industry, all kinds of dragon kiln, steamed bread kiln, gourd kiln and other forms of kilns belong to the category of firewood kiln. Because it consumes wood for combustion, it is not conducive to the protection of environmental resources, and it can rarely be seen except in some traditional ceramic production areas.

Coal kiln: It is an industrial kiln fueled by coal, which was used in large quantities, but was later abandoned or improved due to high energy consumption and high pollution, and used coal gas or heavy oil and light diesel oil as fuel.

Electric kiln: Electricity is used as the energy source, mostly with electric furnace wire, silicon carbon rod or molybdenum disilicide as the heating component, relying on the principle of electric energy radiation and thermal conductivity for oxidation atmosphere firing. Electronic program control, simple operation, good safety performance, suitable for a variety of workplaces, electric kiln is a must-have firing kiln for many pottery studios.

Gas kiln: It is the most widely used kiln today with liquefied gas, coal gas or natural gas as fuel, strong firepower, low pollution, and suitable for firing with different firing atmospheres.

A kiln or stove is a furnace used to fire ceramics and sculptures, or to fuse enamel to the surface of metal objects. Generally, it is built with bricks and stones, and can be made into various specifications according to needs, and can be operated by combustible gas, oil or electricity. Electric kilns are easier to control temperature than those that use combustible gases and oils, but some potters and sculptors believe that the temperature of electric kilns rises too quickly.

The temperature in the chamber of the kiln is measured by a pyrometer or a thermometer cone, and can be seen through the hail front hole.

While this question may be simple, I would like to ask for your advice!

Analysis: The kiln is a kind of calcination production equipment, and the calcined limb raw materials and fuel are co-located in a space, or the combustion area is directly connected with the calcination area. Common ones are brick kilns, lime kilns, and charcoal kilns.

The boiler is a device that indirectly heats water by the combustion of fuel, the fuel is burned in the combustion zone to provide a heat source, and the water is heated into hot water or steam in the "pot cylinder". This special pot barrel has a complete safety device, and the combustion zone has a supporting auxiliary machinery.

The technical content of the boiler is much higher than that of the kiln, and it is inseparable from production and life.
